  Customer A is complaining that routes advertised from the CE2 router are not being received on the CE1 router. The physical topology of the network is CE1-PE1-PE2-CE2. The CE1-PE1 subnet is 172.16.1.0/24. The CE2-PE2 subnet is 172.16.2.0/24. PE1's loopback is 192.168.3.1 and PE2's loopback is 192.168.4.1.Referring to the output in the exhibit, what is the problem?

  A. No LSP exists between PE1 and PE2.

  B. Route targets are not properly configured.

  C. as-override is not configured in the VRFs.

  D. family inet-vpn is not configured on the PEs.

  Correct Answer: A

  In the exhibit, what happens if the source starts sending multicast traffic toward R1 and there are receivers registered at the RP?

  A. R1 encapsulates the multicast packets into a PIM register multicast packet.

  B. R1 encapsulates the multicast packets into PIM join unicast messages.

  C. R1 forwards the multicast packets on the S,G tree towards the RP.

  D. R1 tunnels the multicast packets in PIM register messages toward the RP.

  Correct Answer: D

• Question 113:

  In an interdomain multicast deployment scenario, an RP1 is in AS1 and an RP2 is in AS2. MSDP is configured between RP1 and RP2.In which routing table on RP1 are source- active messages (SAs) received from RP2 by default?

  A. inet.0

  B. inet.2

  C. inet.1

  D. inet.4

  Correct Answer: D

  R3 and R4 want to establish an EBGP session between each other's loopback addresses. They have each configured static routes to the other's loopback address and can ping from loopback to loopback. Their EBGP session is configured with correct neighbor and local addresses. The correct AS numbers have been specified at the [routing-options] hierarchy as well. Considering the topology in the exhibit, which statement is true?

  A. BGP's protocol preference must be adjusted to be lower than protocol static for the session to establish.

  B. Each side must configure multipath for the session to establish.

  C. Each peer must specify a local-as within their EBGP configuration for the session to establish.

  D. Each peer must configure multihop for the session to establish.

  Correct Answer: D

  R2 is announcing the 10.200/16 network to its IS-IS neighbors. No routing policies have been applied to R3. Referring to the exhibit, will R5 have 10.200/16 as an IS-IS route?

  A. Yes; IS-IS level 2 externals are passed from level 2 to level 1 by default.

  B. No; IS-IS level 2 externals are only passed to level 1 if wide-metrics-only is configured on all routers.

  C. Yes; all level 2 routing information is shared throughout an IS-IS domain by default.

  D. No; IS-IS does not announce routes from level 2 to level 1 unless a routing policy is applied.

  Correct Answer: D

• Question 116:

  You are facing BGP scaling issues and decide to add dedicated route reflectors to your network. You notice that VPN routes are not being advertised by your route reflectors. Which three actions can you take to solve this? (Choose three.)

  A. Add a static default route to inet.3 and/or inet6.3 on the route reflectors.

  B. Add a full mesh of MPLS LSPs between all of the route reflectors.

  C. Add MPLS LSPs between the route reflectors and their client routers.

  D. Add a static default route to inet.3 and/or inet6.3 on all of the client routers.

  E. Use rib-groups to add IGP routes to inet.3 and/or inet6.3 on the route reflectors.

  Correct Answer: ACE

  You work for ISP A, as shown in the exhibit, and must configure R1 to use load balancing across both available links to ISP B's network. Which command do you use to finish the configuration?

  A. set protocols bgp group isp-b multipath

  B. set routing-options forwarding-table export per-packet

  C. set protocols bgp group isp-b multihop

  D. set routing-options forwarding-table load-balance

  Correct Answer: A

  B. IPv6 routes will be exchanged over this session.

  C. The local router initiated the BGP session.

  D. BFD keepalive is configured to 30 seconds.

  Correct Answer: AC
